Chargers signed FB Le'Ron McClain, formerly of the Chiefs, to a three-year deal. Free agent Mike Tolbert is likely moving on, which would certainly be good news for the fantasy prospects of Ryan Mathews. McClain thinks he's a tailback, but he's really a true lead-blocker and pass-protector with limited rushing ability. In his career, McClain has averaged just 3.8 yards-per-carry on 329 totes.
